Good that OSM is accurate in cities as well, because in hiking, skiing, or even some ferry routes, OSM simply wins because that's often the only mapping provider to even have _any_ data. Some of my first hand experiences:

- French GR-20 routes. Google maps are laughably empty, while OSM has you covered with almost the same information as the hiking maps you can buy on the trail.

- Anapurna - similar to GR-20 situation. This route gets changed often due to landslides, but there is always some person doing a great job updating information not too late after.

- Volcanoes - OSM maps often contain camping grounds, water sources, etc. This is something I actively contribute too. The level of detail is amazing. Some guides in fact lose potential clients because of this.

OSM is a wonderful feat by all its contributors, and isn't appreciated as much as it deserves.

Is there an easy way to contribute from my phone? If I could just turn the GPS on and let it track my path I’d be able to contribute all of my random hikes that might not be on OSM.
